Title: Smooth rolling device for reducing out of roundness - of workpieces with rotary symmetry using three wheels
Inventor: NEESE PAUL DR ING
IPC: B24B39/00
Filed: 1973-06-29
Abstract: Rolls which support or shape the workpiece are placed around the workpiece in an optimum arrangement, considering the deflection given to the roll which exerts the largest force on the workpiece in relation to the amount of out of roundness, as well as the phase shift given to regularly distributed out of roundness amounts. The planes passing through the lines of contact of the rolls and the centre line of the workpiece make angles with one another of 66 deg., 132 deg. and 162 deg. Optimum deflection is obtained within the defined area on a graph on which the prism angle is plotted against tipping angle.

Title: Antimycotic impregnation of textiles - by applying antimycotic agents as aq. solns. or emulsions
Inventor: SCHNEIDER PETER DR MED
IPC: D06M16/00
Filed: 1973-07-30
Abstract: Impregnation of textile webs (e.g. stockings, socks) with antimycotic substances is effected by applying the antimycotically active components (e.g. 2-naphthyl M-mmethyl-N-(3-toluy)--thiocarbamate, 5-bromo-4'-chloro-salicylanilide or 5-chloro-8-hydroxyquinoline) in the form of an aq. soln/: emulsion subsequent to normal washing procedures. The new procedure ensures that antimycotic agents are well distributed in possible sources of re-infection in the clothing. When the antimycotic substance is applied to stockings or socks, sweat from the feet ensures that the antimycotic agent is transported into the shoes and that fungicidal concns are accumulated in the shoes.

Patent DE-2351071-A1 (DE)
Title: Automatic securing unit for capstan chain - is designed for roller loader in mining operations
Inventor: KUBITZA GUENTER
IPC: E21C29/20
Filed: 1973-10-11
Abstract: The roller loader travels along the face on the face conveyor. After the machine edge of the loader reaches the relief valve and automatically trips it, the cylinder becomes pressureless. The claw-like chain holder for the capstan chain together with the swivel arms is displaced as the machine moves on further. During this process the chain holder opens and releases the chain. After the mining machine has passed the area of the securing unit, the automatic relief valve is automatically closed thereby feeding compressed air again to the cylinder. This causes the chain holder to close as the swivel arms move towards the face. In this way the capstan chain is automatically locked.
Patent DE-2352464-A1 (DE)
Title: Retractable propeller for glider - with direct universal joint to ensure two bladed propeller is accurately located in fuselage
Inventor: SCHEFFEL BERND DIPL-ING
IPC: B64C31/024
Filed: 1973-10-19
Abstract: The two bladed propeller is mounted at the end of a pivoted arm whose bottom end is pivoted about one axis of a universal joint which couples the drive to the engine. The transmission ratio between the universal joint and the propeller is 1:1 so that the propeller can be accurately located by the position of the output shaft of the engine. The support arm is dropped into a slot in the fuselage by tilting about this axis, and can only drop into the slot when this axis is accurately positioned transversely to the fuselage. The propeller is then accurately lined up along the arm so as not to damage the fuselage, and with the universal joint tilted the drive is locked.

Title: Transporter vehicle for variety of liquid or solid goods - has discharge unit with pressure discharge cylinder coupled to bottom of vehicle floor depression
Inventor: SCHROEDER GEORG
IPC: B60P1/56
Filed: 1973-12-29
Abstract: The vehicle has a double floor whose lower part has one or more funnel-shaped depressions at whose lowest point is connected the discharge channel formed as a pressure cylinder. A pressure valve seals off the bottom of the channel which permits a limited amount of the goods to be held there. This amount is ejected into a discharge line by means of a piston located in the upper end position of the channel above the coupling point between funnel and cylinder. The goods are able to be ejected once the closing force of the valve has been overcome and simultaneously the outlet opening in the funnel has been sealed off. Once in the discharge line the goods are transported away by compressed air.

The shoulder is formed from the container material and is integral with it. The shoulder has a downward slope, and may be perforated. It is positioned in the upper part of the container, so that the spoon rests at a shallow angle, with the handle of the spoon resing on the rim of the container and the bowl of the spoon resting on the floor of the shoulder. Below the floor of the shoulder there is a conical tapered section, expanding toward the floor of the container and the lowermost section is cylindrical.

Title: Peptide liq/solid-phase synthesis - by coupling to solid carrier, adding aminoacid to sequence, and again releasing from carrier before starting next cycle
Inventor: FRANK HARTMUT DIPL CHEM DR
IPC: C07K1/04
Filed: 1974-03-20
Abstract: In a process for the stepwise synthesis of peptides, proteins and protein partial sequences (esp. peptide hormones), in each cycle the peptide chain to be lengthened by one amino-acid unit is alternately (a) bound to a solid carrier by the coupling reaction, (b) washed free from non-lengthened peptide chain, soluble excess reagents and by-prods., and (c) again brought into soln., as the lengthened peptide chain by cleaving off the carrier-bound protecting gp. This liq./solid phase synthesis principle may be applied to the synthesis of other macromolecular natural prods., and their analogues, e.g. oligonucleotides, nucleic acids and polysaccharides. The principle may also be applied to the converse procedure of stepwise degradation of macromolecular natural prods., for the purpose of sequence determination using derivativisation reagents versibly bound to solid carriers. Amino-acid derivs. linked at the function not participating in the coupling reaction with a solid carrier via a selectively cleavable grouping are claimed as new cpds. Also new and claimed are cpds. linked to a solid carrier and carrying a grouping are cpds. linked to a solid carrier and acid. The liq./solid phase method of facilitates the removal of unreacted starting peptide, excess reagents etc. between coupling reactions.

Title: Dry cleaning agents contg. glycerol deriv - have improved removal of dirt from textiles etc.
Inventor: HASENCLEVER KASPAR D
IPC: D06L1/04
Filed: 1974-06-01
Abstract: Parent specification described dry cleaning agents based on solvents such as perchloroethylene, 1,1,1-trichloroethane, light and heavy petroleum, etc., with surface active agents and glycerol as additive to remove water soluble dirt. The agents are now improved by replacing the glycerol with a glycerol derivative of formula CH2-OH-CH-OR2-CH2-OR1 where R1 = residue of a saturated or unsaturated 8-18c carboxylic acid and R2 = H or residue of a saturated or unsaturated 8-18C carboxylic acid. The additives, e.g. glycerol monooleate, glyceroldioleate, glycerol dilaurate, etc., give improved cleaning action, do not clog filters in the cleaning fluid system, do not cause foaming during solvent recovery and are compatible with all usual cleaning fluids.
Patent DE-2436225-A1 (DE)
Title: Safety alarm system - uses two isolated metal pieces, one as miniature transmitter other as receiver
Inventor: SUSKA CHARLES RUSSELL
IPC: G08B25/10
Filed: 1974-07-26
Abstract: A safety alarm is formed by using a hinge containing an electronic sensor to guard the required machine, or similar equipment. The hinge shall be closed in the "No Alarm" state, and open in the "Alarm" state. Sensing whether the hinge is open or closed is made by two electrically isolated metal pieces which when closed are touching, or at least in close contact. One of these metal pieces is fed with a high frequency signal, and hence it may be considered to be a miniature transmitter. The other metal piece becomes the receiving aerial. Thus, if no signal is received the alarm is raised.

Title: Ink ribbon movement control system - facilitates positioning of selected colour of multi-colour ribbon in printing position
IPC: B41J35/16
Filed: 1974-09-11
Abstract: The typewriter ribbon is stretched in the printing region by two ribbon guides (2a, 2b) which are wider than the ribbon and are each fitted between the arms of a U-shaped carrier having an additional, lower ribbon guide (3a, 3b) so that the ribbon follows a U shaped course. The two carriers (a, b) can be turned about axes (5a, 5b) passing through their crosspieces parallel to their arms so that the ribbon is effectively shifted along its guides and thereby presents a fresh region of its width to the printing station. The sum of the angles of rotation of the two carriers amounts to 180 deg.
